Hello,

I would like to know how I can save the position after zooming the image. To reproduce the same position at another time.
Or would it be possible to capture the image after zooming?

I found this library to zoom:

But I was unable to locate the function to save the position, nor did I find the function to capture the image.

I would also like to make markings on the image, but these markings need to be editable, I thought of saving only the position where the user clicked, and drawing the marker through a canvas window. Would it be possible to do that?

Thank you.
